There is a lot of snow in the winter where I live. Different kinds of snow; soft, sticky, wet, etc. And ice too. It can get pretty cold: -25 °C (-15 °F). We drop salt, sand and gravel on our roads.
I'm about to buy a bike that I'll be using this winter for commuting to work. What kind of brake will work best in all kinds of wet and icy situations?
I'm interested in braking performance as much as long-term durability.
